Chopped Strand Matting

Fibreglass Chopped Strand Matting - Emulsion, Powder bound and tissue

Fibreglass chopped strand matt is made up of glass strands randomly laid and held together with a binder, either emulsion bound or powder bound. In the case of Polyester and Vinylester resins an Emulsion bound matt is used and in the case of an Epoxy resin a powder bound matt would be used. The binder would then dissolve in the chosen Resin and this would make the Fibreglass Matt (CSM) conform into the shape of the object being laid up on, most commonly the Glass matt sheets are laid on top of each other in layers combined with a resin to form a thicker / stronger part as part of a GRP (Glass Reinforced Plastic) moulding.
